Of the 138 patients enrolled in this study, 59 patients received chemotherapy alone (group A) and 79 patients received haploidentical HSCT (group B).

Figure 3 Relapse, treatment-related mortality, OS, and DFS of patients based on risk stratification (N = 120). (A) Cumulative incidence of relapse. (B) Cumulative incidence of treatment-related mortality. (C) OS. (D) DFS. According to the risk factors for relapse, 138 patients were stratified into low-risk and high-risk groups. Fifty-nine patients without risk factors for relapse were stratified into the low-risk group, 61 patients with risk factors were stratified into the high-risk group, and 18 patients were not evaluated in this analysis because of no MRD monitoring results during follow-up.

Figure 4 Relapse, treatment-related mortality, OS, and DFS of patients based on risk stratification and intervention strategies (N = 120). (A) Cumulative incidence of relapse. (B) Cumulative incidence of treatment-related mortality. (C) OS. (D) DFS. One hundred twenty patients were evaluated in this analysis, but 18 patients were not evaluated because of no MRD monitoring results during follow-up. These 120 patients were further divided into 4 groups: patients without risk factors and receiving chemotherapy (chemo-low, n = 24), patients with risk factors and receiving chemotherapy (chemo-high, n = 20), patients without risk factors and receiving HSCT (HSCT-low, n = 35), and patients with risk factors and receiving HSCT (HSCT-high, n = 41). P1 represents the comparison among 4 groups, and P2 represents the comparison among chemo-low, HSCT-low, and HSCT-high.
